Question

Which equation can be used to find the area of the composite figure pictured below?

7 m
8 m
15 m
: A = 24 (8) + (15 x 7)
= A= 8 (15) + (15 x 7) + }(9 x 8) = A= 8 (15) + 15 (7) +9 (8)
: A = 15 (15) + (9 x 8)

Answer 1

A.

Explanation:

The figure is made up of a rectangle and two triangles.

The dimensions of the 3 polygons are:

Rectangle: 8 m by 15 m

Triangle 1: 15 m base and 7 m height

Triangle 2: 9 m base and 8 m height

Total area =

= [8(15) + 15(7)/2 + 9(8)/2] m^2

Answer: A.
